† Notice:
Stresses above those listed under “Maximum ratings” may cause permanent damage to the device. This
is a stress rating only and functional operation of the device at these or any other conditions above those indicated in
the operation listings of this specification is not implied. Exposure to maximum rating conditions for extended periods
may affect device reliability. This product utilizes CMOS technology with static protection; however proper ESD
prevention procedures should be used when handling this product. Damage can occur when exposed to extremely
high static electrical charge.

The boost converter in Boost mode (normal V
O
= 10V) can draw current pulses of ~0.8A and therefore is very sensitive
to series resistance. The critical components of this resistance are the inductor DC resistance, the internal resistance of
the battery and the resistance in the connections from the inductor to the battery, from the inductor to the LX pin. In
order to function properly under full load at V
DD
= 2V, the total of the inductor and the interconnect resistances should
not exceed 0.3. The internal battery resistance should be no more than 0.5. A low ESR capacitance of 10 µF or more
should be connected in parallel with the battery to average current over the boost converter cycle.
In the above table, wherever a specific V
O
value is listed under test conditions, the V
O
is forced externally with the
inductor disconnected, and the boost converter is not running.
The limits shown are 100% tested at +25°C only. Test limits are guard-banded, based on temperature characterization
to ensure compliance at temperature extremes.
This is the maximum input current that will not cause a logic high or logic low to be asserted.

Horn Delay is the delay between a high signal on HRNEN and the horn output turning ON. The internal circuitry delays
the horn output until the Boost voltage reaches its set point, 10V nominally.
